The head body 10 is made of a first metal material, and a striking panel 11 is formed on the front surface thereof. A plumbing panel 11 is formed on one side of the plumping panel 11, and the heel part 12 forms an extending chin 1 upward. 3. The extending end 13 has a first abutting surface 1 31. The sleeve neck 20 is made of a second metal material, and a coupling hole 21 is formed on the top thereof, and a second abutment surface 22 is formed on the bottom thereof. During assembly, it was chosen to combine the head body 10 and the sleeve neck 20 by friction welding. First, the first and second abutting surfaces are caused by the high pressure of the applied force F.

However, the friction welding method is still easy to cause the following problems in implementation. After friction welding, the first and second abutting surfaces 131 and 22 are caused by the first and second metal materials melting with each other. An intermetallic layer (intermetallic, layer, not shown). Although the intermetallic layer can be used to connect the first and second abutting surfaces 131 and 22, when the welding compatibility of the first and second metal materials (such as stainless steel and titanium alloy) is insufficient, the intermetallic layer is The metallographic structure of the layer is not conducive to the improvement of the bonding strength, and it is easy to cause the structure to crack or reduce the elastic deformation ability. As a result, when the finished golf club head further adjusts the inclination angle A of the neck 20 or is used to swing, the joint position of the head body 10 and the neck 20 may be broken, which affects the yield of the finished product and the use of Life. The shell test proves that when the finished golf club head is subjected to less than 1,000 shells [a ball of standard weight hits the striking panel n of the club body 10 at a ball speed of 50 meters per second _, the club head body Sleeve 20 is a serious defect that tends to crack or break. In addition, when the friction welding method is used in combination with any two adjacent parts of the golf club head, as long as the & _ welding compatibility of the two adjacent parts is insufficient, it will cause the two adjacent parts. The combination structure of the heads of men. It is still necessary to further improve the above-mentioned Gore. In view of this, the present invention improves the above-mentioned disadvantages. The high layer can be connected to the two adjacent portions = f-addition-the medium body.
